Default environment variables in Pipelines | Cloud Platform

Pipelines provides the following environment variables for your use in your YAML file. For example build definition files, see Example Pipelines build definition files.

The following variables are set by the system:

Variable name	Description
`BUILD_DIR`	The target directory into which the build artifact will be generated. Also known as `PIPELINE_DEPLOY_WORKSPACE`.
`CDE_DEPLOY_POLL_TIMEOUT`	Used to set timeouts (in seconds) for the `pipelines-deploy` command without any limit. Default value is 600.
`CI`, `CONTINUOUS_INTEGRATION`	With a value of `true`, indicates that this job is being run in a continuous integration context, rather than initiated directly by a human.
`PIPELINE_APPLICATION_ID`	The application ID for this job’s pipeline.
`PIPELINE_CLOUD_REALM`	The realm in which the application is running.
`PIPELINE_CLOUD_SITE`	The Cloud Platform application name or sitename that corresponds to the application ID.
`PIPELINE_DEPLOY_VCS_PATH`	The branch or tag that holds the output of the job. This variable is also known as `DEPLOY_VCS_PATH`. For more information, see build artifact. When using a GitHub branch during a job launched from a PR, the `DEPLOY_VCS_PATH` includes the PR number as shown in the following example: SOURCE_VCS_PATH="master" DEPLOY_VCS_PATH="pipelines-build-pr-<pr_number>"
`PIPELINE_DEPLOY_WORKSPACE`	The deployment workspace.
`PIPELINE_ENV`	With a value of `true`, indicates that this job is being run in a pipeline context.
`PIPELINE_GIT_HEAD_REF`	A reference to the last commit in the Git repository.
`PIPELINE_JOB_ID`	The job ID for this job. Also known as `PIPELINES_JOB_ID`.
`PIPELINE_PORT_22`	The port mapped to port 22.
`PIPELINE_PORT_8007`	The port mapped to port 8007.
`PIPELINE_SSH_KEY`	Specifies which SSH key will be used in a script. For more information, see Linking to specific SSH keys with a variable and Encrypting keys and variables.
`PIPELINE_STATUS`	With a value of `running`, indicates that this job is running in a pipeline context.
`PIPELINE_VCS_PATH`	The path of the branch specified in the `--vcs-path` argument of the `start` command. Also known as `SOURCE_VCS_PATH`.
`PIPELINES_CURRENT_EVENT`	The name of the current running event. See Events.
`PIPELINES_ENCRYPTED_VARIABLES_AVAILABLE`	A flag to enable or disable decryption of variables.
`PIPELINES_SCRIPT_DATA_FILE`	The name of the file to save script execution data to. Deployment information is stored as shown in the following example if the `pipelines-deploy` command is executed through `acquia-pipelines.yaml`: {"environment":{ "PIPELINES_DEPLOYMENT_NAME":"ode184", "PIPELINES_DEPLOYMENT_LINK": "http:\/\/odetopipelinesode184.prod.acquia-sites.com" }} Note The `PIPELINES_DEPLOYMENT_LINK` variable is not available during runtime.
`SOURCE_DIR`	The source directory containing the build instructions.
`SYNC_DB_POLL_TIMEOUT`	Used to set timeouts (in seconds) for the `pipelines-sync-dbs` command without any limit. Default value is 1000.
